Objectives: This study aimed at evaluating the serum redox status in type 2 diabetes mellitus (T2DM) accompanied with an imbalance in iron concentrations.

Methods: Diabetic patients were grouped according to serum iron levels [normal (DNFe), low (DLFe), and high (DHFe)], and their clinical and redox parameters [total sulfhydryl groups (tSH), uric acid (UA), and total bilirubin (tBILI) as non-enzymatic antioxidants, and malondialdehyde (MDA) and advanced oxidation products of proteins (AOPP) as markers of oxidative stress] were determined.

Results: Glucose and HbA1c levels in the T2DM patients did not differ in function of serum iron. T2DM was associated with reduced tSH levels. In the diabetic patients, tSH, UA, and tBILI negatively correlated with MDA, as well as HbA1c with UA. Accordingly, AOPP and MDA were higher in the diabetic groups compared to the controls. The reduced antioxidant capacity was particularly pronounced in the DLFe group, which was further characterized by lower levels of UA and tBILI compared to the other groups. Subsequently, the level of MDA in the DLFe group was higher compared to the DNFe and DHFe groups. The positive correlation between serum iron levels and the antioxidants UA and tBILI, in conjunction with the negative correlation between serum iron levels and the markers of oxidative stress in the diabetic patients, corroborated the indication that comparatively higher level of oxidative stress is present when T2DM coexists with decreased iron levels.

Conclusions: T2DM-associated redox imbalance is characterized by a decrease in serum total sulfhydryl groups and low serum iron-associated reduction in uric acid and total bilirubin levels, accompanied by increased oxidative stress markers. The relatively noninvasive and simple determination of these parameters may be of considerable interest in monitoring the pathophysiological processes in T2DM patients, and may provide useful insights into the effects of potential therapeutic or nutritional interventions.

Background: The growing demand for natural, health-promoting food products has led to increased interest in integrating nutrient-rich ingredients into everyday foods. The addition of leaves may increase nutrient profile, including essential amino acids, antioxidants, vitamins, and minerals in edible products.

Aim: The study aimed to optimize the addition of leaves in bread, noodles, and pasta and evaluate sensory attributes using a nine-point hedonic scale and nutritional analysis.

Iron overload in transfusion-dependent thalassemia patients represents a significant public health challenge due to its high mortality rate and risks of severe complications. Therefore, developing safe and effective therapeutic modalities for managing iron overload is critical, as current animal models inadequately replicate human conditions. The aim of this study was to investigate the effects of intravenous iron dextran on hepatocyte morphology, liver iron concentration, and serum iron profile changes as a model for hemochromatosis.

We propose an alternative scheme for implementing the antibunching effects of two-magnon bundle in a hybrid ferromagnet-superconductor system, where a magnon mode from the yttrium iron garnet (YIG) sphere interacts with a three-level superconducting qubit via photon virtual excitation in the microwave cavity. With the help of the qubit driving from the ground state to the excited state, the cascaded emission of magnon occurs and then the two-magnon bundle is formed. By analyzing the ordinary and generalized second-order correlation functions, it is found that the antibunched two-magnon bundle could be achieved via properly choosing the system parameters, which is originated from the anharmonicity of dressed energy levels induced by magnon-qubit couplings.

Background: Sepsis-induced acute lung injury (ALI) is a severe clinical condition accompanied with high mortality. Tangeretin, which is widely found in citrus fruits, has been reported to exert antioxidant and anti-inflammatory properties. However, whether tangeretin protects against sepsis-induced ALI and the potential mechanisms remain unclear.
